Vermillion

By using the Dark Gate, humans can entrust their hopes and needs to the darkness. The darkness they call upon is a great and evil power, known as "Demon." With the help of his partner Miroku, the Demon Slayer Kisaki Senju will slaughter every last "Demon" that is called into existence.

[Insert obvious criticism about the lackluster plot & character here] I punched the screen with my imaginative fist whenever the girl repeated that one phrase. As if she was indoctrinated. She clearly has too much red cordial in her system. Let that be a lesson for you kids.

The story and art are great, the characters invoke interest, and the pacing achieves exactly what it needs to with the right timing.

Regarding the "what are demons, and what are demonslayers" topic, I'll explain my interpretation of the mechanics, and what they mean, behind a spoiler tag.

A human who kills another human would turn into a demon. But this is not the case if a human kills a demon, because humans can't kill demons.

Demons can't kill demons because while they can affect miasma, it seems that they cannot truly damage or destroy the demon, due to the core of the demon, the crystallized miasma.

It may be kind of like how using some form matter to break (a rock) another form of matter (another rock) would just scatter or disperse it (into little rocks). I'm assuming miasma (not a rock) will just gather again and restore it's form around the when given the freedom of movement and "oxygen" that nightfall brings (unlike a rock).

This guess-timation may be a little off, but it's probably close enough to the mechanics that it delivers enough of a point.

Regardless of why the rules are as such,and how they work, this next point is confirmed: Humans can't affect miasma, and demons can't do anything lasting either.

However, if a human were to granted the ability to sense and touch miasma, (whether by ceasing to be human or gaining some special quality or trait) then they would lose the issue of being largely unable to affect miasma, while not being bound by the "can't harm other miasma" limitation of demons. This is probably achieved by giving them the essence or qualities of the prime demons, without opening a gate or killing someone. As they have not killed a human till that point, they don't seem to actually turn into beings of miasma, and as such ignore the rules/natural laws that govern said beings.

The reason why a human killing a demon would turn into a demon is makes a lot of sense to me, as demons are basically former humans, albeit faded, warped, and corrupted. So to kill one would mean similar things to killing a human, regardless of the fact that they have blood on their hands and ill intent in their minds.

If "Killing demons is equal to killing humans", and "Killing a human enables one to be warped into a demon" is true, then for demon slayer, "Killing demons enables one to be warped into a demon." Since Demon slayers already have demonic influence affecting them, they likely start losing their human status right away, possibly even without a gate.

Heck, they might have become demons slayers due drawing a gate or making a deal with a demon without killing a human being beforehand, so a gate may have already come into play long beforehand.

Okay, I feel content after disgorging everything that had been bouncing around inside my thick skull. Just get need to get a few dozen tunes, and many bad ideas out of there, and I'll have some peace of mind.

Oh man I completely forgot about this series, thank god for the follow system.

I really need to make a list of note worthy series somewhere physical cause if my follow list somehow bugs out one day I would probably never remember a bunch of promising stories... these are the sort of thoughts that keep me up at night, it's serious stuff.

Do you use MangaUpdates? If so, you can export your lists as .txt files.

Well, seeing as it's neither Old English or Middle English, I suppose it's the English we all know and 'love' (hate to death for it's nonsensical grammar and pronunciations and being the bastard child of a Germanic language, a Romance language, and two Classical languages without any relations to each other. Though I guess it's good that there was no language incest involved).

Anyway, I'm just glad that they picked up the series. It definitely needs proofreading, but I'm not going to complain about free stuff.

Pervy's Plot Summary: After falling madly in lust with the Demon Loli, Miroku, Senju had decided to try to impress her by slaying other demons. Will Miroku be disgusted by his murderous mayhem inflicted on her brethren, or will she finally drop her panties and satisfy every perverted desire that Senju could possibly imagine, including his fantasy of having sex with a jelly filled donut while wearing a ballet tutu as Miroku repeatedly rapes him from behind by sticking her forked demon's tail up his {Name of body part censored by an over-protective and blue-nosed government official.}!!

I have NO relationship with Fallen Syndicate, so they have every right to trash me for my impertinence!! The only, and admittingly feeble, excuse that I can offer is my complete inability to resist f**king with untranslated plot summaries. It is a truly evil and seductive addiction that I have previously only satisfied in my proofreading of chapters that I was responsible for with Death Toll and a few other groups that I have done work for. But like any addiction, I keep wanting MORE!!! And so I gave in to the temptation I found here. I therefore have earned and in fact, totally deserve whatever punishment that the staff of Fallen Syndicate may decide to inflict upon this 57 year old pervert's body!!
